MEANS FOR REENFORCING METALLIC PLATES.

Application filed September 3, 1926. Serial No. 133,435.

Reference is had to the accompanying drawings, which illustrate the preferred form ot' the invention, though it is to be understood that the invention is not limited to the exact details ot' construction shown and described, as it is obvious that various modilications thereotI within the scope of the claims will occur to persons skilled in the art.

My invention relates to means of reen'torcing a metallic plate by forming integral corrugations, embossments or ribs therein and resides in the particular and peculiar configuration and relation of the eorrugations to obtain certain desired results.

An object of the invention is to form and arrange a plurality of corrugations in a metallic plate so as to obtain a desired proportion between strength, rigidity and resiliency. I

Another object is to obtain this result with the least amount of raw material and to provide a linished article ot the least possible weight consistent with strength require ments.

Another object. of the invention is to obtain the desired strength, rigidity and resiliency by forming a metallic plate with integral embossments, each having a wide end and a narrow end and other corrugations or embossments positioned between the narrow ends of adjacent embossments, the wide ends of the einbossments being divided by ribs extending toward the middle of the embossments.

Another object is to provide such a corrugated metallic plate which can be formed by pressing it (when heated, it necessary) between dies which move toward each other in one direction only.

The construction may be used wherever a strong, resilient panel is desired, but is especially adaptable for railway car structures, such as end walls, side or end doors, hopper doors, floors, roots, etc., and while I haveI shown and claimed herein the construction used as an end wall lof a railway car, it is my intention to tile other applications for patents covering the construction used in other railway car structures.

It is well known that the end walls of railway cars are more likely to be broken or otherwise injured than the side walls. This is due to the inertia thrusts and pressures caused by the shifting of the cargoes when the train starts or stops. These thrusts may be local, tending` to distort the end in some particular spot, as, for example, when a piece of piping or lumber shifts lengthwise imparting a blow against the end wall oit the car; or there may be a general tendency 'to break out the end wall as a whole or tear it away from the framing. For the purpose, therefore, of greater strength and durability, car ends have been constructed oi metal plates corrugated or formed with ribs to impart the desired strength, rigidity and resiliency. My construction is especially adaptable to end walls for railway cars (of any type) because it has the strength to resist the continuous pounding oi the shifting loads thereon and has the resiliency necessary to absorb these numerous shocks without distortion. Distortion ot an end wall might bend the brake mast, thereby causing interference with the operation ot the hand brake mechanism. Furthermore, sucli distortion might reduce the end ladder clear-- ance beyond that prescribed by the Interstate Commerce Commission. 1V hen made of several plates secured together the end wall can be made stronger where greater strength. is required. A wooden inside lining is re quired in a railway house carto): blocking the lading to and for compliance with the requirements of the Bureau of Explosives of the'Ame-rican Railway Association. Such a wooden lining can be easily applied to my construction.

In the d awingsz Fig. l shows the end wall of a railway car with my device applied thereon.

Fig. l0 is a section on line 10 10 of Fig. 6. Fig. ll is a section on line 11-11 of Fig. 6. The end wall structure comprises a panel composed ot one or more metallic plates with my particular embossments formed therein.

In Figs. 1 to 5, inclusive, the embossed plates l, 2 and 3 extend trom top to bottom of the end wall and may be formed with integral flanges 4 along the vertical edges of iin which decrease in depth and width toward the middle of the embossments.

3. A metallic plate formed with a plurality of parallel embossments, each having a wide end and a narrow end, and corrugations positioned between the narrow ends ot' adjacent embossments which decrease in depth and width toward the middle ot the embossments and having their sides substantially parallel to the sides of the adjacent embossments, said wide ends being divided by ribs extending toward the middle of the embossments.

l. A metallic plate formed with a plurality ot' parallel embossments, each having a wide end and a narrow end, and corrugations posi-- tioned between the narrow ends ot adjacent embossments extending toward the middle or' the embossments, said wide ends being divided by ribs extending toward the middle of the embossments, said narrow ends and said corrugations being equal in width and spaced apart distances equal to said width.

5. A metallic plate formed with a plurality of parallel embossments, each having a wide end and a narrow end, and corrugations positioned between the narrow ends of adj a-cent embossments extending toward the middle ot' the embossments, said wide ends being 'divided by ribs extending` toward the middle of the embossments, said narrow ends and said corrugations being' equal in width and spaced apart distances equal to said width, and the divided portions of the said wide ends of adjacent embossments being equal in width and spaced apart distances equal to said width.

G. A metallic vplate formed with a plurality of parallel embossments increasing in depth toward their middle, each having a wide end and a narrow end, and corrugations positioned between the narrow ends of adjacent embossments which decrease in depth toward the middle o'lz the embossments, said wide ends bei ug divided by ribs which decrease in depth toward the middle oi the embossments, the lengthsl ol the center lines or' the metal ot every cross section ot the embossed plate being equal between the pla-nes where the embossments begin to terminate into the plane ot' the plate.
